Hey,
when a user starts a process instance in the jBPM Console I'd like to display a form with a select input allowing multiple selection.
I've got the form displayed properly with the multi-select box. However, when submitting the form the corresponding process variable only gets filled with a String containing the first selected value. Any other selected value is discarded, and I would have expected some Collection type instead of a String.
The form is a basic HTML form inside the <process_id>.ftl file:
<form action="complete" method="POST" enctype="multipart/form-data">
<select name="list" multiple="multiple">
<option value="value1">Option 1</option>
<option value="value2">Option 2</option>
<option value="value3">Option 3</option>
</select>
</form>
If I select "Option 2" and "Option 3" in this example and then start the process the list variable is set to a String "value2".
How do I make it return a Collection with all selected values instead?
Thanks in advance,
Martin
